Hi, i’m Looking for a short sf story. The plot is a man is on the tube and there is a crash and he dies and goes to hell. When there he loudly says “I don’t believe it!” . Hell breaks up and he finds himself on the street in front of a bank. He again says “I don’t believe it!” And the street starts to break up. Along comes a gentleman who pushes him under a bus. Can anyone identify the story?
